I always thought that Clockwork Orange was about how you can force someone to be obidient, but not 'good.' Fact is, though Alex led a pretty 'moral' life after his conditioning, he immediately snapped back to his old self once it was removed. He hadn't learned a thing.
You can't control human desire, fools! Bwahahahahahahahaha!
Okay, so perhaps I thought about it a little...EDIT: Oh yeah, I love Full Metal Jacket, too.
2001, however, made the mistake of being so incredibly confusing that anyone who hadn't read the book had their heads explode by the end. Also, it seemed awfully fond of wasting the audiences time...
